T0 (225 whom it may concern:

Be it known that I, DANIEL S. WAUGH, a citizen of the United States, anda resident of Denver, Arapahoe county, Colorado, haveinvented certainnew and useful Improvements in Hoisting-Machines, of which the followingis a specification.

My invention relates to improvements in hoisting-machines of that classwherein rotary motion is imparted to a rope carrying or hoisting drumfrom a steam-engine or other motor through the medium offriction-clutches, and has for its objects the provision in a device ofthe class named, and in connection with the hoisting-drum thereof, ofpeculiarlyconstructcd driving mechanism, means for throwing saidmechanism into or out of operative connection with said drum withoutexert-ing undue end or side pressure or thrust upon the main or drumsupporting shaft and its bearings, means for imparting an increased areaof frictional surface to the drum-driving clutches, and means forimparting the proper adjustment to the several elements comprised in thedevice, all substantially as hereinafter set forth, and illustrated inthe accompanying drawings, wherein similar figures of reference denotesimilar parts.

In said drawings, Figure l is a a top plan view of a hoistingmachineconstructed in accordance with my invention. Fig. 2 representsalongitudinal section th erethrough,taken on the line A B of Fig. 1. Fig.3 is a transverse section thereof, taken on the line C D of Fig. 2,looking in the direction of the arrow on. Fig. 4 represents a transversesectional view taken on the line B F of Fig. 2, looking in the directionof the arrow n. Fig. 5 is a similar sectional view taken on said line EF, looking in the direction of the arrow 0. Fig. 6 represents atransverse sectional view taken on the line G H of Fig. 2, looking indirection of the arrow 1',- and Figs. 7 and 8 represent detached detailviews of parts of the operating, mechanism.

It will be understood that motion may be imparted to my improvedhoisting-machine by any desired form of motor, operated by any desiredpoweras steam, water, wind, gas, &c.-and I have not, therefore, hereinshown, nor shall I hereinafter describe, any particular form ordescription of motor or machine for accomplishing this purpose, but willconfine my description solely to the construction and combination of theseveral elements comprised in the present embodiment of my invention,and to the manner in which said elements co-operate when the machine isin operation.

In thepresent embodiment of my invention I provide the base or bed 1,which may be common both to the hoisting-machine and to the motor whichoperates said machine, with pillow blocks or standards 2 and 3, thatform bearings for the opposite ends of the main or drum carrying shaft4, as shown. I provide the opposite ends of the shaft 4. with collars 5,which bear against the outer surfaces of the pillow-blocks and preventlongitudinal movement of the shaft.

Upon the shaft 4, adjacent to the pillowblock 3, I mount a drum, 6, oneend of which is provided with a flange, 7, about which a brake-strap, 8,extends. (See Fig. 3.) To the flange 7 I secure an annular flangedcasting, 9, the opposite surfaces of which are engaged byfriction-blocks, presently to be described.

Upon the shaft 4, within the flange 7 of the drum, I loosely mount adisk, 10, and provide one surface of said disk that toward the flange 9and upon opposite sides of the middle of said diskwith projectingportions 11, and provide said portions with apertures 12, which receivefriction-blocks 18, preferably of wood, and which at times, hereinafterstated, bear against the flange 9. I provide the opposite surface of thedisk 10, opposite the middles of the projections 11, with lugs or cars14, between which is pivoted in pairs, at 15, angular dogs 16, whichextend thence through apertures 17, formed in the disk 10 outwardly andbetween projecting ears or lugs 18, formed upon the.

opposite ends and sides of a casting, 19, which is loosely mounted uponthe shaft i, adjacent to the disk 10. The ends of the dogs 16 are 9connected by pivoted links 20 with said casting 19, as shown. Betweenand to each pair of dogs 16 I pivot a block, 21, from which extends arod, 22, to and through a spur-wheel, 23, which is mounted upon theshaft 4: outside of the flange f the drum 6, and is held from rotationupon said shaft by a key, 24, as shown The free ends of the rods 22 arescrewthreaded, and adapted to receive adjusting nuts or burrs 25, whichbear against the outer surface of the spur-wheel.

I provide one surface of the spur-wheel 23- that adjacent to the flange9 of the drum 6- with projecting portions 26, having apertures toreceive friction-blocks 27, which in practice are placed opposite theblocks 13 of the disk 10, and cooperate with said latter blocks to clampthe flange 9, as will be hereinafter ex plained.

Rods 28 extend from the casting 19 at opposite sides of the shaft 4outwardly through the spur-wheel 23, and are connected at their outerends with arms 29 and 30, which project from semicircular disks 31 and32, that extend about the shaft 4 outside of the spur-wheel 23, and areconnected together by bolts 33, which extend through laterallyprojecting ears formed on said disks 31 and 32, as shown.

The inner edges of the disk-sections 31 and 32 are placed and operate ina peripheral groove, 34, formed in a short sleeve, 35, which is placedpartly upon a boss or hub, 36, formed upon the spur-wheel 23 and partlyupon a boss which projects from the pillow-block 2. The lattecnamed bossis provided upon its opposite sides, within the sleeve 35, with inclinedperipheral slots 37, into which pins 38 project from the sleeve 35, (seeFigs. 2 and 7,) for a.

purpose hereinafter to be explained. An arm, 38, extends downwardly fromthe sleeve 35, and is connected by a bar or rod, 39, with a lever, 40,pivotally connected to the base 1, as shown.

The outer ends of each of the arms 29 and 30 of the semicircularcastings 31 and 32 are apertured to permit the passage of screwthreadedadjusting-bolts 41 and 42,which pro ject from the spur-wheel 23.

As the drum Bin operation is moved slightly in longitudinal directionupon the shaft 4, its flange 9 might, when said drum is heavily laden,remain for a time in contact with the friction-blocks of the wheel 23,when it is desirable to instantly remove said flange from said blocks.To obviate this objection I provide the shaft 4 within the drum with acollar, 43,-secured in place by a set-screw, 44, and surround said shaftwith a coiled spring, 45, thcfopposite ends of which bear, respectively,against said collar 43 and the inner surface of the drumliead, oragainst a boss formed thereon, as shown in Fig. 2.

I connect the opposite ends of the brake 8 of the flange 7,respectively, with a foot, 46, formed upon the base 1, and an adjustable screw-threaded rod or bar, 47, which connects to a lever, 48,pivoted to said foot 46. The opposite end of. said lever 48 is connectedby links 49 with the lower curved end ofa lever, 50,'also pivoted insaid foot 46, as shown. The teeth of the spur-wheel 23 are engaged bygearteeth formed upon a spur-pinion, 51, which is mounted upon the mainshaft of the motor.

The operation of my device is as follows:

It being understood that the frictionblocks 13 and 27 of the casting 10and spur-wheel 23, respectively, are normally maintained at adistancefrom the flange 9 of the drum, said casting 10 and spur-wheel rotate inunison with the shaft 4, inasmuch as. said shaft andspurwheel are keyedtogether, while the drum 6 It will is maintained in stationary position.also beunderstood that the castings 19,31, and 32, move in unison withthe spur gear-wheel and casting 10. \Vhen it is desired to cause thedrum to rotate, the lever 40 is drawn outward, which action, through theconnecting, bar or rod 39 and arm 3S,causes the sleeve:

35 to rotate upon its bearing, and by said rotation to be moved, throughthe medium of the inclined slots 37 andpin 38, toward the.

spur wheel 23. The connected castings 31 and 32, from their describedconnection with said sleeve 35, will also be moved toward saidspurwheel, and, inasmuch as said castings are, through the rods 28,connected with the casting 19, it also will move: in unison with theparts named, thereby, through the dogs 16, moving the disk 10 in. theopposite directionfi. 6., toward the flange 9. The movement of partsthus described will bring the friction-blocks 13 and 27 of the disk 10and spur-wheel 27, respectively, into engagement.

with the opposite sides of the flange 9. The continued movement of theparts named will cause thelinks 20-to swing into alignment 9 from.engagement with the friction-blocks as will be understood. This latteraction. of the parts described is aided ingreat measure by the spring 45of the drum 6, the said spring operating in manner hereinbeforedescribed.

Movement ot' the lever 40 and its 1 The adjustable bolts 42 and castings31 and 32 serve to draw the spur-wheel backward should such wheel fromanycause not be moved by the action of the parts above described.

In applying the brake S to the drum the lever 50 is drawn backward,which will at first:

rapidly move the lower arm of the lever 48 through the medium-of thelinks 49. As, however, said links will be swung upwardby theabove-described. movement, the upward speed of the point at which saidlinks are connected: to the lever 48 will be gradually decreased untilsaid links are nearly in alignment with said lever, and so operateas alockto holdthe brake-band 8 in close contact with the flange until saidbrake is released therefrom by the opposite movement of the lever 50.

proper adjustment as to length is imparted to the brake-band 8throughithe rod 47..

, The

It will be observed from the foregoing description that the main or drumbearing-shaft is practically free from the longitudinal and lateralstrains consequent in machines of this class upon the direct connectionto such shafts of the clutch-controlling mechanism.

If desired, material other than wood may be employed asi'rictioirblocks.

Modifications in detail of construction may be made in thewithin-described invention without departing from the spirit orsacrificing the advantages thereof-as, for instance, the friction-blocksmay extend entirely-around the casting 10 and wheel 23, respectively, orsaid blocks may be attached to the opposite surfaces of the flange 9.
